SOAP HOLDER FOR DISHWASHING MACHINES Filed oct. 4, 1929 Ntra auf:

E. ERICSSON, F CHICAGO, ILLINOS SOAP HOLDER rota msi-:WASHING MACHINES Application filed October 4, 1929. Serial No. 397,200.

My invention is concerned with soap holdersy for dish washing machines,'etc., and is designed to produce a holder in which a cake of vhard soap can be placed and hot water run-therethrough as it passes to the spraying mechanism, so that hot soap-suds will be sprayed upon the dishes or other articles to be washed.

To illustrate my invention, I annex hereto a sheet' of drawings in which the same reference characters are used to designate identical parts in all the gures, of which,-

Fig. 1 is a top plan View of a'portion of a dish-washing machine embodying my inven- Fig. 2 is aside elevation of the same on the line 2-2 of Fig. 1;

Fig. 3 is a horizontal section on the line 33 of Fig. 2, but on a larger scale; and

"The soap holder `herein shown and described is employed in connection with dishwashing machines of the type shown in my l'prior applications Nos. 299,486, led August 14, 1928; 317,176, filed November 5, 1928, and

323,876,1iled December 5, 1928, now Patents A Nos. 1,7 98,425, 1,798,426 and 1,798,428, dated- March 31, 1931 of which Vapplications the present application may be considered asa quasi-division, since the specific soap holder herein shown and described is not claimed specifically in the foregoing applications,but

only in combination with the dish-washing mechanism therein shown.

In Figs. 1 and 2, 10 represents the back portion of a kitchen sink with which my dishwashing mechanisms are ordinarily employed, and 11 represents the customary hot and cold water mixer, which is provided with piping 12 leading tothe soap holder 13 which is the subject matter of the present application. As in some forms of my dish Washers it is desirable to lift the dish-washing mechanism bodily out of the sink, VI have shown the soap holder as having the supply pipe 14 connected by the swivel joint'l with the piping 12 heretofore referred to. The principal portion of the soap-holder mechanism proper consists of the generally-rectangular casing 13, which may take the form of a castingwith which the pipe 14 is integral, andwliich opens into the top ofthe casing 13 throughl the aperture 16. The generally-rectangular casing 13 is provided'on its under side with the elongated outlet aperture 17 a which opens into the tubular spraying member 18, which Yis provided on its under surface with the perforCs-e Tlf WALnEivIAaL. LINDGREN, oF WAUKnc-AN, ILLINOIS, AssIGNoR or ONE-HALF ro ooi-IN f rations 19 through which the water is sprayed upon the dishes or other articles to be washed passing beneath or above the member, as the f case may be.' One end of' the casing 13 is provided with the rectangular opening 2O into which fits the end of the soap holder proper, which is preferably'formed of sheet metal and is rectangular in cross section and 'of a size to substantially fill the rectangular hollow in the casing 13. This holder 21 is provided with perforations 22 extending along the angle in the top and bottom portions, and with similar perforatons 23 extending along the edges of thev side portions, so thatV water entering the inlet Vport 16 will-'be compelled to spread out over substantially the entire surface of the cake of soapv 24 which will be placed therein, This holder 21 is secured to the cover'or cap 25, which has the overhanging flanges 26 between which and the Aflange 27 formed on the adjacent end of the holder 13 is interposed the-rubber gasket 28 by which the closure is made water-tight.` As ya convenient means vof clamping this endorca-p piece 25 in place, I employ the yoke piece g 29, which has the inwardly-projecting flanges 30 and31 at its endSco-operating with the adjacent surfaces of `the vflange 27 The flange 30 is preferably pivotally connected'to the ange 27 by the screw32, and the set"V screw 33 is threaded through the center ofthe yokev 29, so that when the holderwiththe cake of soap is Vputin .place and the yoke is swung around to .the position shown, thev parts can be securely clampedtogether byk turning the set VScrew 33.l The operation of the apparatus will be apparent, as the hot water flowing from the mixer will perforcebe compelled to flowV all around the cake of soap 24 in reachingthe outlet 17 Pand the sprayer 18, so -that thefvvatersprayed on the dishes will be adequately provided with soap to form a suds.

At the same time, it will be noted that the stream of water flowing from the pipe 14 through the opening 16 does not strike the cake 24 of soap directly, but is deflected and spread out by the adjacent imperforate part of the holder 2l, so that when it finally reaches the soap through the perforations 22 and 23, it has no material velocity, and does not tend to wash the soap away, but merely to dissolve it, so that while suliicient soap is dissolved to make the vdesired suds, it isnot wasted, as I have found it will be if the water from the opening 16 is projected directly on thecake of soap.` Y

While I have herein shown and Vdescribed f my invention as embodied in the form which 'Y from said opening and with said imperforatev .60*

I` at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.

What I claimvas new, and desire to secure by Letters Patent of the United States, is:
